S/R

This script is inspired (published with approval) by "All Lines" ,
Many thanks and gratitude to the original creator!

The difference is that here, you can choose how many Support/Resistance lines you want to see. (0-15, perhaps more in the future)

The script will always show the closest S/R levels, if for example the 'M.P level'
becomes closest to the price while before '1h.ema20' was closer, the line/label will automatically change to the 'M.P level'.

For me, this was a nice practise for my 'array' skills :)

Cheers!
